2y - A / 3 equals a + 3 B / 4 solving for y

melamori03 [73]

To solve for y you need to first multiply both sides by 4. This will give you: 4y - 4A / 3 = A + 3B

Next you need to multiply both sides by 3: 4y - 4A = 3A + 9B

Now you need to add 4A to both sides: 4y = 7A + 9B

Now divide both sides by 4:

Y = 7A/4 + 9B/4
